It has been ten years since the last comprehensive assessment of non-native marine fishes in Florida. Herein, we report sightings of 41 species from Florida coastal waters since the earliest sighting in 1984.

Locks and dams are possible management points to block the spread of invasive Asian carps in the United States. Infusion of carbon dioxide (CO2) into water is one deterrent strategy being considered at navigational structures to reduce upstream fish passage that would not directly interfere with lock and dam operations. The goal of this study was to determine lethal concentrations of CO2 to non-target species. Bluegill (Lepomis macrochirus) and Fathead minnows (Pimephales promelas) were exposed to CO2 continuously for 12 hours using a diluter system. Trials were performed on both species at target water temperatures of 5, 15, and 25°C. See related manuscript for additional details on experimental methods.

Cichlasoma dimerus was only recently discovered in Florida and little is known of its dispersal abilities and potential impacts. Many factors likely contribute to the variability in establishment and spread of non-native fishes in Florida, including biotic (e.g., predation and competition) and abiotic variables (e.g., cold tolerance, low-oxygen tolerance). Of the abiotic variables, cold tolerance is an important regulator of non-native fish geographic ranges in Florida. Its tolerance to cold temperatures is experimentally evaluated and available information on its biology and ecology was synthesized. In the cold-temperature tolerance experiment, temperature was lowered from 24 C by increments of 1 C per hour, mimicking a typical cold weather front. Fish lost equilibrium at a mean temperature of 7.8 C and died at 4.7 C.

Reported here are the metabarcoding read numbers and biomass data assessed from a fish community in a southern Florida pond in Pinecrest Gardens after invasive species eradication and native restocking in 2017 and 2018 in linear regression models. This dataframe contains the number of fish of each species identified, their measured lengths estimated population surface area, and the number of metabarcoding reads (with SD and COV) for each species observed from the sampling date.

Invasive carp pose substantial economic and ecological damage when populations are widespread in freshwater systems within the United States of America (USA). Resource managers in the USA have a limited number of chemical control tools to selectively remove nuisance fish. The present study examined whether Antimycin-A (antimycin) wax encapsulated microparticles could cause selective lethality to invasive carps in a series of laboratory trials, controlled outdoor pond trials, and an experimental pond trial. Datasets include water quality, fish biometrics, fish survival, yttrium consumption, and antimycin microparticle dissipation data.

We provide a comprehensive review of the status of non-native fishes in the central Indian River Lagoon (from Cape Canaveral to Grant-Valkaria, east of I-95) through literature review and field surveys. Historical records exist for 17 taxa (15 species, one hybrid, one species complex). We found historical records for one additional species and collected one species in our field survey that had never been recorded in the region before (and which we eradicated). Thus, we evaluate 19 total taxa herein. Of these, we document range expansion of four salt-tolerant cichlid species, extirpation of six species that were previously recorded from the area and eradication of three species. There was no noticeable change in geographic range for one widespread species and the records for one species are doubtful and may be erroneous. Currently, there is not enough information to evaluate geographic range for four species although at least one of these is established. We provide information on how non-native fishes may interact with or exacerbate phytoplankton blooms and resulting trophic cascades.
